Answer:
31m/s
Step-by-step explanation:
Using the equation of motion
v² = u² + 2gH
H is the height of fall = 49m
g is the acceleration due to gravity = 9.8m/s²
u is the initial velocity = 0m/s
v² = 0² + 2(9.8)(49)
v² = 960.4
v = √960.4
v = 30.9m/s
v ≈ 31m/s
Hence the velocity of water at the turbine is 31m/s
Answer:
NF = 16
Step-by-step explanation:
Since N is the incenter of ΔABC then ND = NE = NF
ND = NE ⇔ 6x - 2 = 3x + 7 ⇔ 6x - 3x = 7 + 2 ⇔ 3x = 9 ⇔ x = 3
Now , we calculate ND:
ND = 6(3) - 2 = 18 - 2 = 16
and because NF = ND then NF is also equal to 16
<h3>the square root of 81</h3>
<h3>Is Nine(9)</h3>
